1. Avaliação do mecanismo de ação antidepressiva e estudo da toxicidade oral aguda e de doses repetidas de hypericum polyanthemum em camundongos / Evaluation of the antidepressant mechanism of action and oral toxicity study of Hypericum polyanthemum in mice
O objetivo deste trabalho foi ampliar o estudo do mecanismo de ação antidepressivo de Hypericum polyanthemum (POL) e de seu composto derivado da classe dos floroglucinóis uliginosina B (ULI). Considerando o potencial desta planta para o desenvolvimento de novos fármacos, realizou-se um estudo pré-clínico de toxicidade aguda e doses repetidas de POL em

2. Changes in the biogenic amine content of the prefrontal cortex, amygdala, dorsal hippocampus, and nucleus accumbens of rats submitted to single and repeated sessions of the elevated plus-maze test
It has been demonstrated that exposure to a variety of stressful experiences enhances fearful reactions when behavior is tested in current animal models of anxiety. Until now, no study has examined the neurochemical changes during the test and retest sessions of rats submitted to the elevated plus maze (EPM). The present study uses a new approach (HPLC) by l

3. The vesicular monoamine transporter 2 is present in small synaptic vesicles and preferentially localizes to large dense core vesicles in rat solitary tract nuclei.
In central neurons, monamine neurotransmitters are taken up and stored within two distinct classes of regulated secretory vesicles: small synaptic vesicles and large dense core vesicles (DCVs). Biochemical and pharmacological evidence has shown that this uptake is mediated by specific vesicular monamine transporters (VMATs). Recent molecular cloning techniqu

4. Extended Methamphetamine Self-Administration in Rats Results in a Selective Reduction of Dopamine Transporter Levels in the Prefrontal Cortex and Dorsal Striatum Not Accompanied by Marked Monoaminergic Depletion
Chronic abuse of methamphetamine leads to cognitive dysfunction and high rates of relapse, paralleled by significant changes of brain dopamine and serotonin neurotransmission. Previously, we found that rats with extended access to methamphetamine self-administration displayed enhanced methamphetamine-primed reinstatement of drug-seeking and cognitive deficit

5. θ, a novel γ-aminobutyric acid type A receptor subunit
γ-Aminobutyric acid type A (GABA-A) receptors are a major mediator of inhibitory neurotransmission in the mammalian central nervous system, and the site of action of a number of clinically important drugs. These receptors exist as a family of subtypes with distinct temporal and spatial patterns of expression and distinct properties that presumably underlie
